It is bad enough a song being stuck in your head, but a story is the worse. We all have imaginations. And it is our imagination which can cause a story to loop in our heads.
I love to create imaginative stories about all sorts of things from being a secret millionaire to an imaginative Professor who discovers major cures for cancer.
These stories can play in my head until they are broken by a new imaginative script.
Our life is a stage so therefore it would be no surprise our minds create surreal scenarios to entertain our inner private world.
Our world is expansive and our imagination infinite.
